BACKGROUND OF THE INVENTION

The present invention relates generally to collapsible structures and specifically to a collapsible container for convenient storage and transportation of items.

The present invention has numerous applications including container, play structure, and shelter. A typical household often encounters the need for temporary storage of garments prior to washing or cleaning. Regardless of the place where laundry or cleaning is done, either at home or in a commercial setting, soiled garments need to be sorted, stored, and eventually transported to a designated place. The present invention can be utilized for garment sorting, storage and transportation. The present invention can also be utilized as an organizer for various objects. For example, the present invention may be used to organize objects normally found in the trunk of a car. Alternatively, the present invention can also be used for other purposes, such as the storage or transportation of toys or other objects. Further yet, the present invention could be used as a child's play structure or pet den structure. Accordingly, its use is multipurpose as both a container and structure.

Numerous devices are known in the art to provide effective storage of soiled garments, for example laundry baskets, conventional hampers, or clothing bags. For example, U.S. Pat. No. 2,625,973 to Weldon et al. teaches a laundry hamper comprising a rectangular frame having upper and lower portions that telescope within one another in a detachable manner. The lower portion includes a base frame, while the upper portion comprises a top frame. A cover is secured by a hinge to the top frame and an outer bag surrounds the rectangular frame. A plurality of small inner bags are provided within the outer bag. U.S. Pat. No. 1,581,888 to Thomas discloses a collapsible receptacle comprising two rectangular wire frames, hingedly secured together, means for holding the frames to form a triangularly shaped structure, and a fabric portion covering the frames and providing an enclosure.

However, all these prior art devices are voluminous in their expanded state, are uneasy to fold or collapse, are still relatively voluminous in their collapsed state, and are difficult to manipulate. The present invention solves the above-mentioned shortcomings and provides a convenient, easy to manipulate, and ergonomic means for storing or transporting garments or other objects.

Other devices are known in the art to be collapsible structures. For example, U.S. Pat. No. 5,560,385 to Zheng teaches a collapsible play structure. This device forms a large cubicle that children can crawl through. However, each cube of the Zheng device utilizes three (3) frame members, preferably four members, to achieve structural integrity. The present invention may be practiced with as few as two frame members.

Additionally, devices are known in the art to provide an enclosure or structure for temporarily containing or for transporting a pet or other objects. For example, U.S. Pat. No. 6,539,895 to Hoagland teaches a portable pet carrier having a top portion, a middle section and a bottom portion made primarily from a molded synthetic material, with the top portion having a handle-like structure for carrying the assembled pet carrier and the middle portion having holes for ventilation and a door or window-like structure for placing a pet in or removing a pet from the carrier. Other pet enclosures are known in the art to be collapsible. These devices commonly have a square footprint and a domed configuration, which creates a pet enclosure that is larger than necessary because of unutilized space. As the size of the enclosure increases, its cost increases and its integrity decreases.

All these prior art pet enclosures are voluminous in their expanded state, are either non-collapsible or are uneasy to fold or collapse, are still relatively voluminous in their collapsed state, and are difficult to manipulate. These configurations require more space, consume more materials, and require stronger collapsible framing than are necessary to efficiently contain or transport a pet or other objects. The present invention solves the above-mentioned shortcomings and provides a convenient, easy to manipulate, and more efficiently sized ergonomic enclosure for containing and transporting pets or other objects, and is adaptable for use in most weather conditions.

SUMMARY OF THE INVENTION

The present invention relates generally to a collapsible structure and specifically to a collapsible structure for storing articles or forming a child's toy and method of making and using the same.

According to the present invention, the foregoing and other advantages are obtained by providing a collapsible structure comprising a plurality of side panels and a floor panel forming an enclosure having an open top. In the preferred embodiment, each side panel comprises a flexible continuous loop frame, a web of material, and an edging material. The edging envelops the frame and is coupled to the periphery of the web. The floor panel is attached to the bottom side of each side panel thus forming the structure.

In an alternative embodiment, each side panel is attached to a side panel separator, which in turn is connected to the next adjacent side panel. The floor panel is attached to both the bottom side of each side panel and to the side panel separators, thus providing means for holding articles within the structure and for supporting the structure in its expanded state.

In another alternative embodiment, a single frame member forms the frame structure for two side panels. Each side panel comprises a web of material and an edging material. The edging material is attached to portions of the web. The edging partially envelops the frame and is coupled to predetermined portions of the periphery of the web. The floor panel is attached to the bottom side of each side panel, thus forming the structure.

In accordance with an aspect of the invention, at least one handle member is coupled to opposite side panels at the open top of the structure. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels. In yet another variation, the edging may be attached to portions of the frame and the handle may be coupled to or looped around the frame at a portion not including edging.

In accordance with another aspect of the invention, an optional storage pouch may be coupled to one of the side panels at the open top of the structure. The present invention is easily collapsed into a compact state and the pouch allows storage of the structure in its collapsed, compact state.

In another alternative embodiment, the collapsible structure further comprises a divider panel, the divided panel being attached to diagonally opposite edgings of the side panels. In yet another alternative embodiment, the collapsible structure further comprises at least two divider panels, preferably arranged substantially parallel to each other and being coupled to opposite side panels to create at least three separate compartments within the structure.

In yet another embodiment, each side panel comprises a flexible, continuous loop frame, and a two-ply web of material. The loop frame is captured between the two layers of web material comprising the two-ply web. The floor panel is attached to the bottom side of each side panel, thus forming the structure. Similarly to previously mentioned embodiments, at least one handle member may be coupled to opposite side panels at the open top of the structure. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels. Further, and as discussed in conjunction with previously mentioned embodiments, the two-ply embodiment may further include an optional storage pouch for receiving the structure in the collapsed state for storage.

A preferred method of manufacturing the collapsible structure includes the steps of attaching each handle member to a side of two opposite webs. The edging is next coupled to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each side of the floor panel is attached to the bottom side of each side panel. Next, a side of each side panel is connected with a side of an adjacent side panel. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state. Optionally, the edging may be non-continuous to allow the handle members to be attached to or looped around the frame member at a non-continuous gap in the edging.

An alternative method of manufacturing the collapsible structure includes the steps of supplying two attached webs of material. Next, edging is coupled to each web such that the edging substantially surrounds the perimeter of each web and forms a channel or pocket through which the frame will later be inserted. An opening in the edging is left along the respective sides where the two webs are contiguous. A two-web side panel is thus formed. After a pair of two-web side panels have been formed, a single frame is inserted through the channel formed by the edging of each two-web side panel. Each frame first is threaded through the edging surrounding one web and then is threaded through the edging surrounding the second, contiguous web. The ends of each frame member are connected, preferably using a crimped butt connector, in a “figure eight” configuration to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state. The second two-web side panel is completed by the same steps. The pair of two-web side panels are connected together and a floor panel is attached along the lower edge of each side panel.

Yet another alternative method of manufacturing the collapsible structure includes the steps of attaching each handle member to a side of two opposite webs. Coupling the edging to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the requisite number of side panels has been formed, each corner of the floor panel is attached to one end of each side panel separator. Next each side panel is connected with one side of the floor panel and with two adjacent side panel separators. The frame for each side panel is inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible structure its ability to freely stand in a rigid, expanded, upright state. Optionally, the edging may be non-continuous to allow the handle members to be attached to or looped around the frame at a non-continuous gap in the edging.

Yet another alternative method of manufacturing the collapsible structure includes the step of first joining two webs together leaving a small opening for receiving the continuous loop frame member. This forms a side panel. The requisite number of side panels are formed and attached along their side edges. Next, each side of a floor panel is attached to the bottom side of each side panel. The frame for each side panel is inserted through the small opening. Finally the opening is closed. Optionally, one or more handles may be attached to or formed in the side panel, frame or both.

In the alternative embodiment where the first web is continuous and non-interrupted and the second web has an annular configuration, the first step comprises attaching the first web to the second web along their outer peripheries to form a side panel. Next, the requisite number of side panels are formed and attached along their side edges. Next each side of a floor panel is attached to the bottom side of each side panel. The frame for each side panel is inserted into the peripheral opening formed between the first and second webs. Again optionally, one or more handles may be attached to or formed in the side panel, frame or both.

From the expanded state, the structure can be folded and collapsed for storage or transportation. The preferred steps of collapsing the structure include grasping opposite corners of the floor panel and biasing one corner toward the other until all side panels are adjacent and overlay each other. The structure is now partially collapsed but each side panel is still in an expanded state. Next, the optional handle members and the floor panel are inserted in between any two of the adjacent overlaying side panels. By rotating two opposite corners of the flattened, overlaying side panels in opposite directions while biasing the two corners toward each other, the structure will form three overlaying circular loops folded adjacently. Finally, the three overlaying loops may be placed into an optional storage pouch. The pouch prevents the structure from springing back into its fully expanded condition. Alternatively, the three overlaying loops may be maintained in the collapsed state by way of an elastic band or other retaining device.

Summary of the Invention (with Sleeves)

In yet another embodiment, the collapsible structure is preferably an enclosure being rectangular in shape and comprises a top panel, a bottom panel, two side panels, a front panel having a door, and a rear panel. The top panel, bottom panel, two side panels, front panel, and rear panel are connected to one another to form a substantially rectangular enclosure having the door for ingress and egress. The top panel, bottom panel, and two side panels each comprises a flexible, continuous loop frame, a web of material, and an edging material. The edging envelops the frame and is coupled to the periphery of the web. The top and bottom web preferably comprises a web being continuous and non-interrupted. Each side panel web preferably comprises a web being a continuous and non-interrupted mesh material. The front panel is attached to the front side of the top panel, bottom panel, and two side panels.

Summary of the Invention (w/Sleeve and Separators)

In an alternative embodiment, each of the top panel, bottom panel, and two side panels are attached to a side panel separator, which in turn is connected to the next adjacent panel. The front panel is attached to both the front side of the top panel, bottom panel, and two side panels, and to the side panel separators. The rear panel is attached to both the rear side of the top panel, bottom panel, and two side panels, and to the side panel separators, thus providing means for holding pets or other objects within the enclosure and for supporting the enclosure in its expanded state.

Similarly to previously mentioned embodiments, at least one handle member may be coupled to an edge or edges of the top panel or side panels. Alternatively, the handle may be coupled to only one side panel or may be an aperture formed within one or more of the side panels or top panel. In yet another variation, the edging may be attached to portions of the frame and the handle may be coupled to or looped around the frame at a portion not including edging.

However, it should be noted handle members are not required to practice the present invention. Further, and as discussed in conjunction with previously mentioned embodiments, the two-ply embodiments may further include an optional storage pouch for receiving the enclosure in the collapsed state for storage.

Summary Methods (Method w/Sleeve)

A preferred method of manufacturing the collapsible enclosure includes the steps of attaching each handle member to a side of two opposite webs. The edging is next coupled to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the top panel, bottom panel, and two side panels have been formed, each side of the rear panel is releasably attached to the rear side of the top panel, bottom panel, and two side panels. Next, a side of the top panel, bottom panel, and two side panels is releasably connected with a side of each adjacent panel. Next, each side of the front panel is releasably attached to the front side of the top panel, bottom panel, and two side panels. The frame for the top panel, bottom panel, and two side panels is inserted through the channel formed by each edging.

Summary Methods (Method w/Separators)

Yet another alternative method of manufacturing the collapsible enclosure includes the steps of attaching each handle member to a side of two opposite webs. Coupling the edging to each web such that the edging surrounds the perimeter of the web and forms a channel or pocket through which the frame will later be inserted. After the top panel, bottom panel, and two side panels have been formed, each corner of the rear panel is releasably attached to the rear end of each side panel separator. Next, each of the top panel, bottom panel, and two side panels are releasably connected with one side of the rear panel and with two adjacent side panel separators. Next, each corner of the front panel is releasably attached to the front end of each side panel separator. Next, the front side of each of the top panel, bottom panel, and two side panels are releasably connected with the front side of the front panel and with two adjacent side panel separators. The frame for the top panel, bottom panel, and two side panels are each inserted through the channel formed by each edging. The ends of each frame member are connected, preferably using a crimped butt connector, to give the collapsible enclosure its ability to freely stand in a rigid, expanded, upright state. Optionally, the edging may be non-continuous to allow the handle members to be attached to or looped around the frame at a non-continuous gap in the edging. Additionally, an optional storage pouch for receiving the enclosure in the collapsed state for storage may be releasably attached to any of the panels.

Summary Methods (Method 2 Ply Closed)

Yet another alternative method of manufacturing the collapsible structure includes the step of first joining two webs together leaving a small opening for receiving the continuous loop frame member. This forms one of the top panel, bottom panel, and two side panels. The requisite number of panels are formed and attached along their side edges. Next, each side of a rear panel is attached to the rear side of the top panel, bottom panel, and two side panels. Next, a side of the top panel, bottom panel, and two side panels is releasably connected with a side of each adjacent panel. Next, each side of a front panel is attached to the front side of the top panel, bottom panel, and two side panels.

The frame for each panel is releasably inserted into the peripheral opening formed between the first and second layers. Again optionally, one or more handles may be attached to or formed in any of the top panel, side panels, and frame. Additionally, an optional storage pouch for receiving the enclosure in the collapsed state for storage may be releasably attached to any of the panels.

Summary Steps of Collapsing

From the expanded state, the enclosure can be folded and collapsed for storage or transportation. The preferred steps of collapsing the enclosure include grasping opposite corners of the rear panel or front panel and biasing one corner toward the other until the top panel, bottom panel, and two side panels are adjacent and overlay each other. The enclosure is now partially collapsed but the top panel, bottom panel, and two side panels each are still in an expanded state. Next, the optional handle members and the rear panel and front panel are inserted in between any two of the adjacent overlaying expanded panels. By rotating two opposite corners of the flattened, overlaying panels in opposite directions while biasing the two corners toward each other, the enclosure will form three overlaying circular loops folded adjacently. Finally, the three overlaying loops may be placed into an optional storage pouch. The pouch prevents the enclosure from springing back into its fully expanded condition. Alternatively, the three overlaying loops may be maintained in the collapsed state by way of an elastic band or other retaining device.

DETAILED DESCRIPTION

Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention that may be embodied in other specific structure. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.

The present invention, a collapsible structure 10, is illustrated in FIGS. 1 through 4.

As shown in FIG. 4, the structure 10 comprises four rectangular side panels 20, a floor panel 50, and two handles 60 and 62. The side and floor panels 20 and 50 are connected to one another to form a substantially rectangular structure having an open top 16.

Referring to FIGS. 1 and 2, each side panel 20 further comprises a frame 22, a web 24, and an edging 26. The frame 22 is flexible, preferably formed from a sufficiently stiff yet resilient material such as spring steel wire or plastic, and is contained within the channel or pocket 25 formed by the edging 26 (best seen in FIGS. 6 b and 24 b). The frame 22 forms a continuous loop. Preferably, the frame 22 has a rectangular cross-section, but a material with a different geometric cross-section can be used. The web 24 is a flexible foldable material, such as nylon cloth or nylon mesh, but can be any suitably flexible material. The nylon, or other flexible material, may be solid or perforated. The perimeter of the web 24 is stitched to the edging 26 such that the edging 26 forms a pocket 25 about the periphery of the web 24. The edging 26 is a foldable, but stretch-resistant material capable of housing the frame 22 within its pocket 25. The edging 26 has two ends 27 and 29.

A seam cover 28, also made out of a foldable stretch-resistant material, may be provided to cover the ends 27 and 29 of the edging 26, thereby protecting the frame 22 from escaping out of the edging 26. As shown in FIG. 1, the seam cover 28 is also stitched to the web 24.

As shown in FIG. 3, the floor panel 50 is also a foldable web of material and has a generally rectangular shape. The floor panel 50 has four corner sections 52, 54, 56, 58 and is attached to four substantially perpendicular sides 51, 53, 55, 57 of each side panel 20. The floor panel 50 provides means for holding the garments or other objects (not shown) within the structure 10 and for supporting the structure 10 in its expanded state.

Referring now to FIGS. 5-8, one embodiment of the collapsible structure 10 is shown. This embodiment includes side panel separators 40 located between each side panel 20. However, it should be noted that the side panel separators 40 are not required to practice the present invention. The side panel separators 40 are shown to be substantially longitudinal, each including an end 42 attached preferably by means of stitching to one of the corner sections 52, 54, 56, 58 of the floor panel 50. The other end 44 of each separator 40 corresponds to the open top 16 of the structure 10. The side panel separators 40 are preferably formed from a stretch-resistant material similar to the material used for the seam covers 28 or the edging 26.

As shown in FIG. 6A, each rectangularly-shaped side panel 20 includes a top side 32 corresponding to the open top 16 of the structure 10, a floor side 34 attached to one of the sides 51, 53, 55, 57 of the floor panel 50, and two lateral sides 36 and 38. Referring just to FIG. 6A, each lateral side 36 and 38 is attached to a side panel separator 40 adjacent to the side panel 20.

As depicted in FIGS. 4 and 8, the handles 60 and 62 have both ends connected to the top side 32 of two opposing side panels 20. The handles 60 and 62 are formed from a stretch-resistant material having a mesh web that extends between a portion of each strap side. The handles for the present invention are not limited to the particular type shown in FIGS. 4 and 8. Several alternative embodiments are shown in FIGS. 9 through 12, illustrating different handle members. In FIG. 9, the handle members 60 and 62 are straps stitched to opposite side panels. FIG. 10 depicts an alternative embodiment wherein the handle members 60 and 62 are apertures or openings formed in the webs 24 of two opposite side panels 20. In FIG. 11, one handle member 60 is shown as a strap coupled to diagonally opposed side seam separators 40. In FIG. 12, the handles 60 and 62 are preferably stitched directly to the webs 24 of two opposite side panels 20.

As shown in FIG. 13, an optional storage pouch 70 may be formed from a foldable material, such as nylon mesh, and stitched to the side 32 of one of the side panels 20. The storage pouch 70 is dimensioned to accommodate the structure 10 in its collapsed state as later described.

Although stitching is presented as the preferred means for attaching or connecting the elements of the structure 10 and permitting relatively convenient folding of the structure 10, it is to be understood that other methods of attachment can be used in this invention. Such other methods may include heat sealing, gluing and the like. Accordingly, construction of the collapsible structure should not be limited to stitching alone.

FIGS. 14 through 17 depict an alternative embodiment of the collapsible structure 12. The structure 12 further includes a divider panel 80. Divider panel 80 is connected to opposite side seam separators 40 thereby dividing the interior of the structure 12 into two separate chambers.

FIGS. 18 to 21 show a second alternative embodiment of the collapsible structure 14. The structure 14 comprises six side panels 20 and two divider panels 80 and 82. The divider panels 80 and 82 are arranged substantially parallel to one another. Each divider panel 80 and 82 is made out of a foldable material, such as nylon mesh, and has two sides 86 and 88 stitched to webs 24 of two opposite side panels 20. The divider panels 80 and 82 separate the interior of the structure 14 into three separate compartments for improved sorting and storage of objects.

FIGS. 22 to 30 show various stages in the manufacturing process of the preferred embodiment of collapsible structure 10. Referring to FIGS. 22A and 22B, the step of stitching the handle 60 to the top side 32 of two (2) of the webs 24 is shown. Specifically, the stitching is shown at 90.

In FIG. 23, a seam cover 28 is partially stitched to side 21 of each of the four (4) webs 24. In the two (2) webs having handles 60 or 62, the seam cover 28 is placed and sewn opposite to the handle 60 or 62. Each seam cover 28 is preferably placed in the middle of the side 21 and includes a flap or unstitched portion, but it is to be understood that it could be placed anywhere on any side of each of the webs 24. Referring now to FIG. 24B, the edging 26 is then folded in a channel-like fashion around the periphery of the web 24 and stitched to the web 24, surrounding the perimeter of the web 24. The stitching is shown at 30. The stitched edging 26 forms a pocket 25 around the periphery of each web 24. In the preferred embodiment, each structure 10 requires four (4) webs 20. The two (2) sides including the web 24, edging 26 and seam cover 28 are shown in FIG. 24 a and the two (2) sides including the handle 60, web 24, edging 26 and seam cover 28 are shown in FIG. 25. Stitching of each edging 26 starts and ends at the seam cover 28, thereby leaving a small space between ends 27 and 29 of each edging 26.

In FIGS. 26A and 26B, the next step involves stitching each corner section 52, 54, 56, 58 of the floor panel 50 to the end 42 of each side panel separator 40. The stitching is shown at 46. Now referring to FIGS. 27 and 28, the step of attaching each of the four side panels 20 by means of stitching to the floor panel 50 and the side panel separators 40 is shown. The two (2) side panels 20 containing the handles 60 and 62 should be positioned opposite each other with the handles 60 and 62 facing inwardly toward each other. First, the floor side 34 of each of the side panels 20 is stitched to one of the sides 51, 53, 55, 57 of the floor panel 50 as shown in FIG. 23. Still referring to FIG. 23, next the lateral sides 36 of each of the side panels 20 is stitched to the corresponding adjacent side panel separator 40. As shown in FIG. 28, once the first lateral side 36 of a side panel separator 40 is stitched on one side, the second lateral side 38 of another side panel separator 40 is stitched to the other side. The resulting enclosure 92 is shown in FIG. 29.

As discussed previously, the structure 10 may be constructed without the side panel separators 40. In constructing the embodiment without side panel separators 40, the two (2) side panels 20 containing the handles 60 and 62 are positioned opposite each other with their handles 60 and 62 facing inwardly toward each other. The floor side 34 of each of the side panels 20 is stitched to one of the sides 51, 53, 55, 57 of the floor panel 50. Next the lateral sides 36, 38 of each of the side panels 20 are stitched to an adjacent side panel 20 thus forming the structure 10 having an open top 16.

The final steps of the manufacturing process of the present invention involve inserting the frame 22 in one of the open ends 27 or 29 of each of the edgings 26 as shown in FIG. 30. The frame 22 is passed through the edging 26 and around the periphery of each of the side panels 20. The ends of the frame 22 are joined together such that the frame 22 forms a continuous loop. In the preferred embodiment, the frame ends are connected by inserting each end into a butt connector and crimping the connector. Finally, the unstitched portion of each seam cover 28 is stitched to side 21 of each web 24 and over the ends 27 and 29 of each edging 26, thereby protecting the frame 22 from escaping the edgings 26.

From the expanded state, the structure 10 may be folded into a collapsed state for storage and transportation. FIGS. 31 to 36 show various steps for collapsing the structure 10. Referring to FIG. 31, the first step requires grasping opposite sides of the structure 10 and biasing one toward the other until all side panels 20 are adjacent and overlay each other. The next step includes inserting the handle members 60 and 62 and the floor panel 50 in between any two of the adjacent overlaying side panels 20 is shown in FIG. 32. It is important to make sure that the storage pouch 70 remains outside of the collapsed side panels 20. In the preferred embodiment, the resulting partially collapsed structure 10 is a stack of four side panels 20. FIGS. 33 and 34 show the next step of rotating two opposite corners 101 and 103 of the partially collapsed structure 10 in opposite directions while biasing the corners 101, 103 toward each other. The structure 10 will first twist and then will rotate to form three overlaying circular loops 150 situated adjacently as shown in FIG. 35. The final step, shown in FIG. 36, is the insertion of the collapsed structure 10 into the storage pouch 70.

When the collapsed structure 10 is removed from the storage pouch 70, the frame members 22 will bias the structure 10 into its fully expanded state. Again, the fully expanded state of the embodiment is that shown in FIG. 4.

Referring now to FIGS. 37-40, the preferred embodiment of the collapsible structure is shown as reference numeral 100. The structure 100 includes four side panels 20 and a floor panel 50. The side panels 20 and floor panel 50 are connected to one another to form the structure 100 having an open top 16. Two side panels 20 are connected to form a pair 84 of side panels 20. Two pair 84 of side panels 20 are preferably used to form the structure 100. The preferred embodiment in these views includes a single modified frame 22′ for each pair 84 of side panels 20. Each side panel 20 further comprises a web 24 and an edging 26. As in the previous embodiments, the web 24 is a flexible foldable material, such as nylon cloth or nylon mesh, but any suitable material may be used. The material may be solid or perforated, as desired. The frame 22′ is flexible, preferably formed from a sufficiently stiff yet resilient material such as spring steel wire or plastic, and similarly to the previously described embodiments, is contained within the channel or pocket 25 (seen in FIG. 55) formed by the edging 26. The edging 26 is a foldable, but stretch-resistant material capable of housing the modified frame 22′ within its pocket 25. The edging 26 has two ends, 27 and 29. The frames 22′ are each formed in a “figure eight” configuration as will be discussed in more detail. As shown in FIG. 53 b, the frame 22′ has a rectangular cross-section, but a material with a different geometric cross-section may be used. For purposes of example only, an alternative cross-section, seen as circular, is shown in FIG. 54 b.

FIGS. 41-43 illustrate another embodiment of the two frame structure 100. In this embodiment, a seam cover 28 is stitched to each web 24 and over the open ends 27 and 29 of each edging 26, thereby protecting the frame 22′ from escaping the edging 26. Each seam cover 28 includes a flap or unstitched portion, and it is to be understood that it could be placed anywhere on any side of each of the webs 24, depending on the insertion point of the frame 22′ defined by the open ends 27 and 29.

FIGS. 44-49 illustrate the various stages in the manufacturing process of the two-frame structure 100 shown in FIGS. 37-40. To form the first pair 84 of contiguous side panels 20, two integrally formed, contiguous webs 24 seen in FIG. 44, are provided. Edging material 26 is then attached to the web 24 perimeter and a portion of the contiguous border 72, as shown in FIG. 45. The edging 26 is folded in a channel-like fashion around the periphery of the web 24 and stitched to the web 24 with stitching 30. The folded and stitched edging 26 forms a pocket 25 (seen best in FIG. 55) around the periphery of the web 24. Stitching of each edging 26 starts and ends at the open ends 27 and 29, preferably located at the contiguous border 72.

The next steps of the manufacturing process of the present invention involve inserting the frame 22′ in one of the open ends 27 or 29 of the edging 26 as shown in FIG. 47. The frame 22′ is passed through the edging 26 and around the periphery of each of the side panels 20. As the frame 20′ completes its circuit around the first side panel 20, it crosses over itself at open end 27, 29 to form a “figure eight” as it enters the edging 26 of the second panel 20. When the frame 22′ is completely inserted in the pocket 25 surrounding both panels 20, the ends of the frame 22′ are joined together at a helical portion 68 such that the frame 22′ forms a continuous loop. In the preferred embodiment, the frame ends are connected by inserting each end into a butt connector 64 and crimping the connector 64 (see in particular FIG. 52). The steps shown in FIG. 44-49 are completed a second time to form a second pair 84 of contiguous side panels 20. As illustrated in FIGS. 50 51 b, the first and second pair 84 of contiguous side panels 20 are positioned to form the structure 100. The floor panel 50 is attached to the floor side 34 of panels 20, as shown particularly in FIG. 50, and the first and second pair 84 of contiguous side panels 20 are attached to one another along the edging 26 of lateral sides 36, 38 of panels 20. As shown in FIG. 51 b, an optional storage pouch 70 may be formed from a foldable material, such as nylon mesh, and stitched to the top side 32 of one of the panels 20. The storage pouch 70 is dimensioned to accommodate the structure 100 in its collapsed state, as will be described.

As will be observed in FIGS. 52-54 b, the frame 22′ includes a helical portion 68, 68′. The helical portion 68 has a relatively flat cross section whereas the portion 68′ may be formed with a circular cross section. The helical portions 68, 68′ provide a means for expansion and contraction of the frame 22′ which allows facile folding and unfolding of each individual pair 84 of panels 20, as will be later described.

FIGS. 56-60 b illustrate an alternative manufacturing process of the two-frame structure 100. Seen particularly in FIG. 56, four integrally formed, contiguous webs 24 are provided. As shown in FIG. 57, edging material 26 is then attached to the web 24 perimeter and a portion of the contiguous border 72, leaving insertion areas 74 defined by open ends 27 and 29. Similarly to the previous embodiments, the edging 26 is folded in a channel-like fashion around the periphery of the web 24 and stitched to the web 24 with stitching 30. As seen in FIG. 55, the folded and stitched edging 26 forms a pocket 25. Stitching of each edging 26 starts and ends at open ends 27 and 29.

The next step in the alternative manufacturing process involves inserting a frame 22′ at each insertion area 74, in an open end 27 or 29 of the edging 26. As described with reference to FIG. 46, each frame 20′ of the embodiment shown in FIG. 58 completes its circuit around a panel 20, crosses over itself at insertion area 74, and enters a second panel 20 in open end 27 or 29. After the frame 22′ is completely inserted in the pocket 25 surrounding two adjacent panels 20, the ends of the frame 22′ are joined together to form a continuous loop. A crimped butt connector 64 retains the ends. The alternative method of manufacture is completed as seen in FIGS. 59 and 60 in a manner similar to that described with reference to FIGS. 50 and 51. The method may optionally include a storage pouch 70, as seen in FIG. 60 b.

As discussed in reference to the primarily described embodiments shown in FIGS. 1-30, the two frame structure 100 of FIGS. 37-61 may, from the expanded state, be folded into a collapsed state for storage and transportation. FIGS. 31 to 36 show various steps for collapsing the structure 10, and the two frame structure 100 is similarly collapsed, as shown in FIGS. 62-67. Referring to FIG. 62, the first step requires grasping opposite sides of the structure 100 and biasing one toward the other until all side panels 20 are adjacent and overlay each other. The next step includes inserting the handle members 60 and 62, if provided, and the floor panel 50 in between any two of the adjacent overlaying side panels 20 is shown in FIG. 63. It is important to make sure that the storage pouch 70, if provided, remains outside of the collapsed side panels 20 (as shown in FIG. 33). The resulting partially collapsed structure 100 is a stack of four side panels 20. FIGS. 64 and 65 show the next step of rotating two opposite corners 101 and 103 of the partially collapsed structure 100 in opposite directions while biasing the corners 101, 103 toward each other. The structure 100 will first twist and then will rotate to form three overlaying circular loops 150 situated adjacently as shown in FIG. 66. The final step, shown with reference to structure 10 in FIG. 36, is the insertion of the collapsed structure 10, 100 into the storage pouch 70, if provided.

When the collapsed structure 100 is removed from the storage pouch 70, the frame members 22 will bias the structure 100 into its fully expanded state.

An alternative folding step may be seen in FIG. 67 wherein the two frame structure 100 may be finally secured in the collapsed state by way of an elastic flexible band 66.

FIGS. 68-70 c, inclusive, illustrate a further embodiment of the collapsible structure 10. Each side panel 20 comprises a frame 22, a web 24, and an edging 26. As in the previously mentioned embodiments, the frame 22 is flexible, preferably formed from a sufficiently stiff yet resilient material such as spring steel wire or plastic, and is contained within the channel or pocket 25 formed by the edging 26 (as seen in FIG. 6 b). The perimeter of the web 24 is stitched to the edging 26 such that the edging 26 forms a pocket 25 substantially about the periphery of the web 24. At least one of the webs 24 includes edging 26 having a non-continuous gapped portion 48. The gap 48 defines an area wherein the frame 22 is exposed. As illustrated in FIGS. 70 a-70 c, a handle 60 may be inserted in the gap 48 between edging ends 27 and 29. After insertion in gap 48, the handle 60 is looped around the frame 22. As seen particularly in FIG. 70 c, the handle 60 may be stitched at 78 for securement after insertion in gap 48. Alternatively, the handle 60 may be affixed to itself or the frame member with adhesive or another securement means. Both handles 60 and 62 may be attached in this manner.

It is to be understood that although not specifically illustrated in the Figures, handles 60 and 62 may be secured by looping around the frame 22 of any of the foregoing embodiments.

FIGS. 71-77, inclusive, illustrate a further embodiment of the collapsible structure 200. The structure 200 preferably includes four side panels 20 and a floor panel 50. The side panels 20 and floor panel 50 are connected to one another to form a substantially rectangular structure having an open top 16.

Referring to FIGS. 71 and 72 it may be seen that each side panel 20 comprises a frame 22 and a two-ply web 124. As in the previously mentioned embodiments, the frame 22 is flexible, preferably formed from a sufficiently stiff, yet resilient, material such as spring steel wire or plastic. In the embodiment shown in FIGS. 71-77, and as seen particularly in FIG. 72, the frame 22 is captured between the two layers 202, 204 of the two-ply web 124. The frame 22 forms a loop. The looped frame 22 may or may not be continuous. Preferably, and similarly to the previously described embodiments, the frame 22 has a rectangular cross-section, however material having a different geometric cross-section may be used. The two layers 202, 204 of the web 124 may be made from any flexible, foldable material, including but not limited to nylon or cotton cloth. The nylon or other flexible material is preferably solid, rather than perforated to more easily retain the frame 22 between the layers 202, 204 of the web 124; however a suitably perforated material may be used.

The top 206 and bottom 208 perimeter of the two-ply web 124 is preferably stitched to seam cover 128 such that the bottom 208 perimeter is thereby attached to the floor panel 50. The seam cover 128 is preferably made from a foldable stretch-resistant material.

As may be seen particularly in FIGS. 71 and 73, handles 60 and 62 may be attached to the top side 206 of two opposing side panels 20. As discussed with regard to previous embodiments, the handles 60 and 62 are formed from a stretch-resistant material having a mesh web that extends between a portion of each strap side. It is to be understood that the handles for the present invention are not limited to the particular type shown in FIGS. 71-77, but may include other designs as previously illustrated in FIGS. 9-12, by way of example.

As may be seen in FIGS. 71, 73-76, an optional storage pouch 70 may be formed from a foldable material, such as nylon mesh, and stitched to the side of one of the panels 20. As in the previously described embodiments, the storage pouch 70 is dimensioned to accommodate the structure 200 in its collapsed state.

Although stitching is presented as the preferred means for attaching or connecting the elements of the structure and permitting relatively convenient folding of the structure 200, it is to be understood that other attachment means may be used in this invention.

FIG. 77 depicts a variation of the embodiment illustrated in FIGS. 71-76. In this view, the structure 200 further includes frame stitching 210. The frame stitching 210 preferably extends through the two layers 202,204 of the two-ply web 124. The frame stitching 210 is preferably substantially parallel to the frame member 22 and, as shown, may comprise a pair of substantially parallel stitch lines 212, 214. When the frame stitching 210 is presented as a pair of stitch lines 212, 214, the frame member 22 is preferably positioned between the stitch lines 212, 214 such that the frame 22 is captured within a stitch channel 216. This arrangement more positively positions the frame 22 between layers 202, 204. It is to be understood that while the Figures illustrate continuous stitch lines 212, 214 of frame stitching 210, the invention may be practiced using a non-continuous or interrupted stitch line as well.

FIGS. 78-80 illustrate another embodiment of the collapsible structure 400. The structure 400 preferably includes four side panels 20 and a floor panel 50. The side panels 20 and floor panel 50 are connected to one another for form a substantially rectangular structure having an open top 16.

Referring to FIGS. 78 and 79, it may be seen that each side panel 20 comprises a frame 22 and a two-ply web 124. As in the previously discussed embodiments, the frame 22 is flexible, preferably formed from a sufficiently stiff, yet resilient, material such as spring steel wire or plastic. In this embodiment, and as seen particularly in FIG. 79, the frame 22 is captured between the two layers 402 and 404 of the two-ply web 124. The frame 22 forms a continuous loop. Preferably, and similarly to the previously described embodiments, the frame 22 has a rectangular cross-section; however material having a different geometric cross-section may be used. The two layers 402 and 404 of the web 124 may be made from any flexible, foldable material including but not limited to nylon or cotton cloth. The nylon or other flexible material is preferably solid, rather than perforated to more easily retain the frame 22 between the layers 402 and 404 of the web 124; however a suitable perforated material may be used. In this embodiment, layer 402 is a continuous, non-interrupted web of material. Layer 404 is annular in shape having an opening 406 in its central region. The opening 406 can be of any shape and size. If desired, an edging 408 may be stitched around the inner perimeter of the opening 406.

The top 410 and bottom 412 perimeter of the two-ply web 124 is preferably stitched to seam cover 128 such that the bottom perimeter is thereby attached to the floor panel 50. The seam cover 128 is preferably made from a foldable stretch-resistant material.

As best shown in FIG. 80, frame 22 is captured between the layers 402 and 404. In this embodiment, each frame member 22 may be easily removed from the collapsible structure. This allows the structure to be, for example, washed, by hand or in a machine. The frame 22 can then be reinstalled between the layers 402 and 404.

As may be seen particularly in FIG. 78, handles 60 and 62 may be attached to the top side 410 of two opposing side panels 20. As discussed with regard to previous embodiments, the handles 60 and 62 are formed from a stretch-resistant material having a mesh web that extends between a portion of each strap side. It is to be understood that the handles for the present invention are not limited to the particular type shown in FIG. 78, but may include other designs as previously illustrated in FIGS. 9-12, by way of example.

As may be seen in FIG. 78, an optional storage pouch 70 may be formed from a foldable material, such as nylon mesh, and stitched to the side of one of the panels 20. As in the previously described embodiments, the storage pouch 70 is dimensioned to accommodate the structure 400 in its collapsed state.

Although stitching is presented as the preferred means for attaching or connecting the elements of the structure and permitting relatively convenient folding of the structure 400, it is to be understood that other attachment means may be used in this invention.

As best shown in FIGS. 108-110B, frame 22 is captured between the layers 862 and 864, and the layers 866, 868. In this embodiment, each frame member 22 may be easily removed from the collapsible enclosure 800. This allows the enclosure 800 to be, for example, washed, by hand or in a machine. The frame 22 can then be reinstalled between the layers 862 and 864, and 866 and 868.

Referring to specifically to FIG. 110A, the perimeter of each two-ply web 824, 825 is preferably coupled to seam cover 128, by way of stitching, as a non-limiting example, such that the layers 862 and 864, and the layers 866 and 868 are thereby attached to the seam cover 128. The seam cover 128 is preferably made from a foldable stretch-resistant material.

As may be seen particularly in FIG. 107A, handles 60 and 62 may be attached to an edge or edges of the top panel 802 or side panels 806, 808. As discussed with regard to previous embodiments, the handles 60 and 62 are preferably formed from a stretch-resistant material, and may have a mesh web that extends between portions of each strap side. It is to be understood that the handles for the present invention are neither limited to the particular type nor location shown in FIG. 107A, but may include other designs as previously illustrated in FIGS. 94-97, by way of non-limiting example.

As may be seen in FIGS. 111-113, an optional storage pouch 70 may be formed from a foldable material, such as nylon mesh, and releasably coupled to the rear side 834 of any one of the panels 802, 804, 806, 808, although the storage pouch 70 may be attached to any of the panels 802-812. As in the previously described embodiments, the storage pouch 70 is dimensioned to accommodate the enclosure 800 in its collapsed state.

Although stitching is presented as the preferred means for releasably attaching or connecting the elements of the enclosure 800 and permitting relatively convenient folding of the enclosure 800, it is to be understood that other conventional releasably attachable means may be used in this invention. Other conventional attachment mechanisms, such as but not limited to heat sealing, gluing, hooks, fasteners, buttons, snap-fit engagements, loops, snap buckles, zippers and ties, can also be used without departing from the spirit and scope of the present invention.

As discussed in reference to the described embodiments shown in FIGS. 1-30, the enclosures 600, 700, 800 of FIGS. 81A-115 may, from the expanded state, be folded into a collapsed state for storage and transportation. FIGS. 31 to 36 show various steps for collapsing the structure 10, and the enclosures 600, 700, 800 are similarly collapsed. Referring to FIG. 31, the first step requires grasping opposite sides of the enclosure 600, 700, 800 and biasing one toward the other until the top, bottom, and side panels are adjacent and overlay each other. The next step includes inserting the handle members 60 and 62, if provided, and the front panel 610, 710, 810 and the rear panel 612, 712, 812 in between any two of the adjacent overlaying panels, and is shown in FIG. 32. It is important to make sure that the storage pouch 70, if provided, remains outside of the collapsed panels (as shown in FIG. 33). The resulting partially collapsed enclosure 600, 700, 800 is a stack of the top, bottom, and side panels. FIGS. 33 and 34 show the next step of rotating two opposite corners 101 and 103 of the partially collapsed enclosure 600, 700, 800 in opposite directions while biasing the corners 101, 103 toward each other. The enclosure 600, 700, 800 will first twist and then will rotate to form three overlaying circular loops 150 situated adjacently as shown in FIG. 35. The final step, shown with reference to structure 10 in FIG. 36, is the insertion of the collapsed enclosure 600, 700, 800 into the storage pouch 70, if provided.

When the collapsed enclosure 600, 700, 800 is removed from the storage pouch 70, the frame members 22 will bias the enclosure 600, 700, 800 into its fully expanded state.

An alternative folding step may be seen in FIG. 67 wherein the enclosure 600, 700, 800 may be finally secured in the collapsed state by way of an elastic flexible band 66.

The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described.
